Hydratdannelse og metanproduksjon fra gasshydrat - produksjonsmetoder og resistivitetsutvikling
(The University of Bergen, 2009-11-20)
Ved høye trykk og lave temperaturer kan vannmolekyler danne strukturelle bur rundt et gjestemolekyl. Denne substansen er da i fast form og kalles hydrat. I naturlig forekomst av gasshydrat er metan det vanligste gjestemolekylet. ...
Acoustic effects on pulse forming in ultrasound transit time gas flowmeters at no flow conditions
(The University of Bergen, 1995)
Permittivity measurements using dual open ended coaxial probes
(The University of Bergen, 2012-11-19)
The motivation for this study has been to conduct a feasibility study on a measuring device to monitor hydrate formation close to the inner surface of a pipe where a multiphase hydrocarbon fluid mixture is flowing. This ...
ATLAS Detector Monitoring with Jets
(The University of Bergen, 2009-10-02)
The purpose of this thesis was to provide a high level software framework for detecting large problems with the ATLAS detector at the LHC and estimate the jet resolution from the f irst data. The result was the program ...
Modeling of Transport, Chemical and Electrochemical Processes in Solid Oxide Fuel Cells
(The University of Bergen, 2009-09-11)
The working of solid oxide fuel cells (SOFCs) involve fluid dynamics, chemical reactions and electrochemical processes. These phenomena happen simultaneously in complex and sophisticated structures of the SOFC main ...
Dose distribution in the thyroid gland following radiation therapy of breast cancer-a retrospective study
(BioMed Central, 2011-06-09)
Purpose: To relate the development of post-treatment hypothyroidism with the dose distribution within the thyroid gland in breast cancer (BC) patients treated with loco-regional radiotherapy (RT). Methods and materials: ...
Suppression of ψ(2S) production in p-Pb collisions at √sNN=5.02 TeV
The ALICE Collaboration has studied the inclusive production of the charmonium state ψ(2S) in proton-lead (p-Pb) collisions at the nucleon-nucleon centre of mass energy √sNN = 5.02TeV at the CERN LHC. The measurement was ...
Direct two-photon double ionization of H2
(American Physical Society, 2012-06-05)
We have studied the process of direct (nonsequential) two-photon double ionization of molecular hydrogen (H2). Solving the time-dependent Schr¨odinger equation by an ab initio method, total (generalized) and singlediffe ...
A study of mass reconstruction in Z°→τ+τ-
(The University of Bergen, 2010-05-28)
Neutrinos escaping detection is one of the main problems in mass reconstruction with tau leptons. They must be neglected or corrected for in some way. This thesis discusses two methods of handling the neutrinos in ...
Properties of Terrestrial Gamma ray Flashes. Modelling and Analysis of BATSE and RHESSI data
(The University of Bergen, 2012-06-15)
This thesis objective is to study Terrestrial Gamma ray Flashes (TGFs), which are short burst (∼ 1 ms) of gamma-radiation from thunderstorms first discovered by Fishman et al. . The measured photons energies in ...
